Abstract

A fastener member ( 10 ) including: a base portion ( 11 ) having a surface ( 15 ); and a plurality of locking members ( 12 ) vertically provided on the surface, the locking members locking with a subject to be coupled so as to mechanically couple to the subject to be coupled; wherein the locking member includes a shaft portion ( 20 ), projecting from the base portion, having a pair of side faces ( 22 A, 22 B) that are opposite each other in a first direction (x) and, as viewed from the surface, diverge in a second direction (y) orthogonal to the first direction, and a barbed portion ( 21 ) provided on each of the pair of side faces; and, as viewed from the surface, the barbed portion provided on at least one of the side faces of the pair of side faces extends in a direction intersecting the first direction and the second direction.

First claim

What is claimed is:

1. A fastener member comprising: a base portion having a surface; and a plurality of locking members vertically provided on the surface, the locking members locking with a subject to be coupled so as to mechanically couple to the subject to be coupled;
the locking member including:
a shaft portion, projecting from the base portion, having a pair of side faces that are opposite each other in a first direction and, as viewed from the surface, each face extending in a second direction orthogonal to the first direction; and
a barbed portion provided on each of the pair of side faces; and
as viewed from the surface, the barbed portion provided on at least one of the side faces of the pair of side faces extending in a third direction non-parallel to each of the first direction and the second direction; and
wherein a plurality of the barbed portions is provided on at least one of the side faces.

2. The fastener member according to claim 1 , wherein a recess for hooking the subject to be coupled is formed on the surface side of each of the barbed portions.

3. The fastener member according to claim 2 , wherein as viewed from the surface, (a) the locking members are disposed in a lattice-like manner, (b) each of the barbed portions includes a portion extending farther in the second direction than the shaft portion, or both (a) and (b).

4. The fastener member according to claim 3 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

5. The fastener member according to claim 2 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

6. The fastener member according to claim 1 , wherein, as viewed from the surface, the locking members are disposed in a lattice-like manner.

7. The fastener member according to claim 6 , wherein, as viewed from the surface, each of the barbed portions includes a portion extending farther in the second direction than the shaft portion.

8. The fastener member according to claim 6 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

9. The fastener member according to claim 1 , wherein, as viewed from the surface, each of the barbed portions includes a portion extending farther in the second direction than the shaft portion.

10. The fastener member according to claim 9 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

11. The fastener member according to claim 1 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

12. The fastener member according to claim 1 , wherein a recess for hooking the subject to be coupled is formed on the surface side of each of the barbed portions.

13. The fastener member according to claim 12 , wherein as viewed from the surface, (a) the locking members are disposed in a lattice-like manner, (b) each of the barbed portions includes a portion extending farther in the second direction than the shaft portion, or both (a) and (b).

14. The fastener member according to claim 12 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

15. The fastener member according to claim 1 , wherein as viewed from the surface, (a) the locking members are disposed in a lattice-like manner, (b) each of the barbed portions includes a portion extending farther in the second direction than the shaft portion, or both (a) and (b).

16. The fastener member according to claim 15 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

17. The fastener member according to claim 1 , wherein each of the barbed portions provided on the pair of side faces is provided so as to be symmetrical around the shaft portion.

18. The fastener member according to claim 1 , wherein the extension direction of each of the barbed portions provided on at least one of the side faces of the pair of side faces is configured of directional components of both the first direction and the second direction.

19. The fastener member according to claim 1 , wherein each of the barbed portions provided on at least one of the side faces of the pair of side faces extends so as to widen to an outer side from the shaft portion as the barbed portion approaches the surface.
